Why the study?
The study was conducted to independently evaluate the claim that the Cigna StressWaves Test, an AI-based tool assessing psychological stress from speech, is a clinical-grade tool.
Does the Cigna StressWaves Test reliably and validly measure psychological stress compared to the Perceived Stress Scale in adults?
Does the Cigna StressWaves Test reliably and validly measure psychological stress compared to the Perceived Stress Scale in adults?
The Cigna StressWaves Test demonstrated poor test-retest reliability and poor convergent validity with the Perceived Stress Scale, failing to support claims of clinical-grade performance.
No takes yet. Share an insight, caveat, or question.
CSWT lacks repeatability and convergent validity; challenges commercial "clinical-grade" claims and leaves rigorous validation of AI stress tools open.
Yawer et al. (2023) studied this question.
